Title: Carbonate slurry processing system - using sugar refinery boiler flue gases as conveying medium and combustion air preheating
Inventor: MUELLER GERHARD W DIPL CHEM DR
IPC: C02F11/12
Filed: 1976-11-24
Abstract: Lime-contg. waste sludge, e.g. the so-called carbonate slurry of the sugar industry, is processed by recycling a side stream from the dryer to the mixer. Dry particles, sepd. in a dust extractor from the dryer flue gases, are recycled to a heat treatment chamber. Boiler flue gases are used as conveying gas for the dry particles and to preheat the combustion air for the combustion chamber. Pulverised coal is added as fuel to the dry particles before entry in the heat treatment chamber. The heat energy requirements are thereby reduced still further. Clogging of the recuperator by quicklime is thereby eliminated.

Title: Energy economising drive for vehicle - has IC engine to periodically drive hydraulic pump, and hydraulic motor used as pump on downhill stretches
Inventor: FAHRION WALTER
IPC: B60K17/10
Filed: 1977-06-30
Abstract: An engine is coupled by a clutch to the vehicle drive wheels and to a hydraulic pump. The pump delivers fluid to an hydraulic motor which also drives the vehicle. for starting, both engine and motor drive the vehicle. As soon as sufficient hydraulic pressure is available the engine is disconnected and left to idle while the hydraulic motor alone drives the vehicle. The engine is reconnected only when hydraulic pressure falls again. When the vehicle descends hills and the drive acts as a brake the hydraulic motor acts in reverse as a pump to restore the pressure in the cylinder. The kinetic energy of the vehicle is thus also used to assist the drive system.

Inventor: GROEGER DETLEF PROF DR
IPC: A61K31/48
Filed: 1978-01-13
Abstract: The ergot akaloids having a cyclol side chain are frequently used in medicine. It is the aim of the invention to obtain the alkaloid ergosine, which was not so easily accessible until now, by a convenient process and thus to supply it for pharmaceutical use. This is achieved with the aid of the strain IMET PA 134 of the species Claviceps purpurea (Fr) Tul. This was isolated from saprophytic alkaloid-free wild types by double mutation with the aid of a special selection route (e.g. on the basis of morphological changes). The said strain forms, in aerobic submerse or emerse culture in liquid nutrient media which contain a carbon source, a nitrogen source and mineral salts, at 20-30 DEG C, pH 4.0 - 6.2 in the course of 10-35 days, an alkaloid mixture of 90% ergosine/ergosinine and 10% clavine alkaloids with a total alkaloid content of 300-350  mu g of alkaloid per ml of nutrient solution.
